Sahih al-Bukhari, Hadith 2901 ⓘ
Narrated Abu Huraira: While some Ethiopians were playing in the presence of the Prophet, `Umar came in, picked up a stone and hit them with it. On that the Prophet said, "O `Umar! Allow them (to play)." Ma`mar (the subnarrator) added that they were playing in the Mosque.
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنْ مَعْمَرٍ، عَنِ الزُّهْرِيِّ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ بَيْنَا الْحَبَشَةُ يَلْعَبُونَ عِنْدَ النَّبِيِّ صلى الله عليه وسلم بِحِرَابِهِمْ دَخَلَ عُمَرُ، فَأَهْوَى إِلَى الْحَصَى فَحَصَبَهُمْ بِهَا. فَقَالَ " دَعْهُمْ يَا عُمَرُ " . وَزَادَ عَلِيٌّ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ فِي الْمَسْجِدِ.
